Abstract

The invention discloses a vehicle-mounted terminal simulation test system applicable to detection of overload and overspeed of various types of vehicles. In the system, signal output terminals of a GPS simulated positioning unit, a timing unit, a vehicle type recording unit and an engine parameter acquisition unit are connected with signal input terminals of an overload and overspeed calculation processor unit by virtue of a first wireless communication transmission unit; a signal output terminal of the overload and overspeed calculation processor unit is connected with a first alarm reminding switch and is connected with a signal output terminal of an overload warning unit by virtue of a second wireless communication transmission unit; and the signal output terminal of the overload and overspeed calculation processor unit is connected with a second alarm reminding switch and is connected with a signal output terminal of an overspeed warning unit. The vehicle-mounted terminal simulation test system applicable to the detection of overload and overspeed of various types of vehicles overcomes the defects of existing static and dynamic overload monitoring and a laser radio frequency technology and a radar speed measurement system and realizes vehicle real-time online overload and overspeed precise monitoring according to different road conditions and different vehicle types.

Description

technical field [0001] The invention relates to the technical field of actual vehicle testing and analysis of vehicle terminal products, in particular to a terminal simulation experiment system capable of detecting overload and overspeed of various types of vehicles. Background technique [0002] At present, there are two methods of monitoring over-limit and overloading of vehicles: static and dynamic. Although static weighing has high precision, when the weighing device is working, it needs to intercept and lead a small number of vehicles from the normal traffic flow to the static weighing site. Weighing inspection, and because of its large scale and eye-catching, often make it easy for many overloaded and overloaded vehicles to escape; at the same time, static weighing takes a long time, which is likely to cause traffic jams, and it is especially difficult to take advantage of the expressway. [0003] Vicious traffic casualties caused by overloading and speeding of vehicle...
